To allwliowtc'tmayconcerm; Y

Be it known that I, RALPHS Twoeoon,

Y .a citizen ofthe `UnitedStatesfresidinglat' Berkeley, in the county ofAlameda and ff Stateof Californiaghave invented certain new andusefulImprovements in Household Furnaces, of'whichthefollowing is a. speci-1ication., h y I My'inventionfrelates to the class of fur- Ylonaceswhich, .especially intended vfor heat- Ving buildings,` areappropriately termed household furnaces. I

1 One objectV of my .invention'is to provide afcoin'bination" hot-airand hot-water or 15 steam furnace,1thus making use of the advantages ofboth types of `heating` systems.Y Another object of 'my invention Y1s topro-V vide,1 in such a'conibination furnace, means forfapportioning, at'will, the heat derived 20,. from the combustion of the fuel, between theair and water heating'portions ofthe furnace."`Still another Objectistofprovide a i furnace `having the'g'reatestl possiblether- Vmalefficiency.

My` combination :well adaptedfor use-insuch buildings as hotels, vinwhichthe parlors', dining rooms,

and other public rooms, which mustV be kept warm continuously, areheated by hot an' leddirectlyfrom. the furnace, while the morereniotebedroom `are'heated :by steauiV or hot water controlled at will bytheoccupants.- iInsuchbuildings also, the use of my furnace, a `constantsupply of steam isv available in the kitchen, laundry, and other servicerooms. My furnace may also be used in the saine manner for heatingresidences, the halls, parlors, etc. being heated by'hot air leddirectly fromthe furnace located beneath theserooms, and the more remotebed rooms being heated by steam or hot water. i Y

My furnace isso constructed that the hot aseous products of combustionmay `be'used rst for heating ,theV water for the hotk water or Vsteamsystem,`a'nd then alarge4 portion ofthe heat remaining in the hot gases,

which' is ordinarily lost in al simple steainf furnace, Vmay be used,forheating then air furnace -is particularly now fully describe by4reference to the'accompanying drawings, wherein-- Figf l `is apartlybrokenfront elevation of my furnace.'V y

` Fig. 2 isa vertical taken on the line2--2 of Fig. V3. Y

Fig. 9 is a perspective view of a portion of the damper con-trollingmeans. F igrlO is a' vertical section of the lire-box, taken on the line10,-10 of Fig. 2. Fig. ll is a sectional detail showing th section ofVthe saine,l

broken sectional'plan of the Y arrangement of the waterldrurns when thefurnace is adapted for-hot water rather than steam heating. 2 A

In the drawings,the reference'numeral 1 designates the .outer shell orcasing of my furnace, which is preferably made of brick or other similar`material to prevent unnecessary radiation of heat.` W

Within the 'lower left-hand portion of the casing, as viewed inV Figs.Vl and 2, is a lire boX 2, constructed in any well known manner inaccordance with Vthe type of .fuel which is to be used.` .'AbovethereboX is a flat horizontal bafflev or deflector wall 3, Figs. 2 and 3,preferably constructed of refractory-'tile or lire brick, each brick 4beingprovided upon opposite'edges with semicircularundencnt recesses 5,as shown in Figs. Z and 8, so positioned that the two recessesofadjoining bricks form a cylindrical.

.recess for thel reception of the head of a bolt 6, these bolts passingthrough and being securedto horizontal supporting beams 7, Figs. 2` 3, 7and 8.4 ,Thus when the bricks 4g are assembled, they form a.con tinuousrefractory baille, thus protecting. the supporting beamsw andbolts 6from the heat of the fire.-

The deflector wall 3 extends far enough toward the right, away from thefire-box 2,

of fa pressure controlled 'regulating device 48. Said regulatingdevicemay be of any -welliknown form, and is connectedbyfa `pipefl9 with thesteam drum V12'. These parts are so connected that any decrease in steampressure will open jthe damper', thereby `increasing the rate ofcombustion of the rire, and Vice Versa.,

, in the operation pass damper 20, Fig.` 2, `is set ina verticalposition, thereby closing` the by-pass V19,`all Vthe hot 'gaseousproducts o'i' combustion pass over the waterv coilsv 9', and thenthrough the airheating lues 22. It more heat isl desired from the hotair system, thedamper is moved to vopen said.. by-pass 19 slightly,

thereby allowing some ofthe'hot gases to pass directly to the airheating lues 2 2. At

thesametime the automatic regulator 48 opens the damper further, toincrease the fire and keep the temperature of the steam Vconstant. It'no steam is required, the damper 2O can be set to bypass all the hotgas'es to the air kheating lues 22, and the damper 35 regulated by hand.

LA furnace comprising a shell; a uelburning member in the shell; Y aVdeflector wall for the products of combustion overly-` ing said fuelburning member; an air-heating member within the shell overlying saiddeilector wall and exposed to the heat of Vthe products of combustionpassing V.around the end of the delector wall, in their course to theirexit romgthe shell; a'water-heating member at ,one side of the-fuelburning member4 and exposed' to therrheat from the Y products, ofcombustion passingrunder the deflector wall; and a damper disposed toselectively include and exclude said water heating AmeinberV fromfthecourse Vofthe v products of combustion.V Y

3. A furnace comprising a shell; a l'uelburning member in the shell; adeflector wall for the products or' combustion, over.-
